To. ALL WHOM IT MAY ooNcERN:

Be it known that I, 4NEPSON W. GItEEN, of Cortland vVillage, Cortlandcounty, State" of `New York, have invented a new and improved mode ofSeizing orGrrappling Rods, Tubes, Pins, Posts, or Piles, for the purposeof withdrawing the same from the ground or from timber perpendicularly,and a newand` improved macl1ine,' and a new and improved combination oflevers and arrangement of fulcra, forv the purpose of'applying and'using the said, modes of grappling, and for withdrawing the said rods,tubes,-pins, posts, or piles, as aforesaid;

and I do `hereby declare that therfollowing is a full, clear, and exactdescriptionof the construction and operation of the same, referencebeing had to themannexed drawings, making a part of this specification,in which` i l Figure 1 is the different parts of the Iachine incombination; and the other figures show the profile and sections. K

The nature of my invention consists in providing the scifi-adjustinggrapple, B Bso constructed that when the levers, D D, are applied incombination on opposite sidesof the thing to he grappled, and the shortarms of the levers liftvupon the opposite jaws ol' the grapple, that therst ciieet of the levers, DD, is to close the i jaws of the grapple, BB, upon the thing to be withdrawn and s'eizelit,"and as the power of thelevers.,` D D, is` i increased theigrappl'epB B, is raised, takingtherod, tube, or other `thing so seized, along with it; and when theshort arms of the levers are again lowered tliegrapple opens, by forceoi' gravity, and follows thellevers to i its original position, to beagain grappled and raised, as before, each time raising the 4thingsoseized, thus i adjusting'itself to its work by the simultaneous working'of thelevers, D D, like the handles of a pump, and `in so constructingan'dicombining the two or more levers, D D, that the rod, tube,` die.,shallbeilifted in aperpeni dicular direction, that is, in a line incontinuation of the line of the thing to be withdrawn, thus, among otheradvantages, avoiding the resistance occasioned by the side applicationof the power, by which is secured, not i only a great gain in theeiective force of 4each separate lever, but again by the combination;and infthe com il struction and varrangement of the two fulcra, C C, bywhich the power or eiective distance of the levers,`D D, can be changedas the one or the other may be most desired'; and of constrncti'ngthebed, F F F, with the ,p

standards, A A, by which the grapple, B B, and levers, D D, andtillcra,- C G, canbe applied as indicated. l

. `V I construct my self-adjusting grapple, B B, of iron, steel, orwood, or,other ec'luivalenh` with the arms, b b, which move freely upand down in the grooves, a a, in the standards, A r, with .the view ofkeepinglthe jaws of the grapple, BB, in position to receive the levers,D D. The holethrough` the grappleI lnakeafile surface and equal to thesize of the rod or thing to be grappled, but cut away at the centralparts .of the jaws `to Hatten and make it less than a circle in orderthat it will close upon the rod, &.c., before the jaws meet. `I so unitethe jaws of the grapple, B B, by hooks at thebottom, that the axis ofmotion shall be below the lower `face of the jaws and so adjusted thaton the application of the levers the whole of bth of theilesuri'acestshall be brought l l into contact with the thing to hegrappled. When it is desired to use the grapple, BDB, alonefor thepurpose i of a. clamp to receive the blow of a falling weightn drivingthe rod or tubein constructing wells, or similar 1 cases, I simplydetach the grapple, B B, and reverse it and adjusting it to thethingjt'obe driven in the reversed position and slightly clamp it in thedesired position by means of clamp-screws added for the purpose, one onp l l each side, which screw into one jaw and move easily through theother, outside the file surface, to allow the grapple to seize therbaror tube when the weight strikes it, Aand then closes and grapples itupon thesame principle as when the levers are applied. I construct mybed, F F F, of iron, or other equivalent material, with a i hole throughthe bottoin to receive the rod or thing to be withdrawn, with theadjustable fulcra, C C, and the standards, A A, which operate as beforedescribed, and the levers, D D, of the same material. Theffulcra.,

-C C, have a series of grooves on the under sides, which tit tocorresponding grooves' in thebed, for the purpose of retaining them inplace, a section of vwhich is shown in iig. 4. When the fbed, F F F, in`combination with i the grapple, B B, and fulcra, C C, andglevers, D D.,are to be used for withdrawing small rods from timbers, or pins fromship planks and frames, I'dispen'se with the adjustable fulcrum and castthem. with the bed entire,` and for convenienceattaeh to the levers, DD, rods perpendicularly to` them, which turn upon themselves `in the pgrooves of the top of the fulcra, C C, and are attached to the bed byextending into sockets onV each Vsideof` the levers in the bed; and inthis case the hole and file surface 0f the grapple is made at thebottom` equalto the size of the largest rod or pin likely to begrappled, and tapering to apoint at the top of the grapple, thus` makingthe machine small, compact; and applicable to general purpeses; and thewhole maehne, in this or the other form,A may be used as a jack, bywhichis secured a great gain of power.

What I claim isl Y 1. The self-adjusting grapple B B, the adjustablefulcra, C C, in combinaltion with the levers D D.

2. I claim the frame F F F, including the standard A A, in combinationwith the grapple B B, the adjustv able fulcra C C, and the levers D D,for the purposes described,
